#Letters Patent No, 94,912, dated September 14, 1869.

IMPRcvEMENT 1N Inennt..-c'JoTJPLIrres.

The Schedule referred to in these Letters Patent and-making part of the same.

To all whom it may concern.-

Be it knownl that I, luanrurr` R; RAPP, of Philadelphia, Pennsylvania, have invented an Improved Carlitige-.Coupling and I'do hereby declare'the following to he afull, clear, and exact description of the same..

My invention consists of a'oam-lever hung to acarriage-clip, and arranged for compressing a rubber block to tlieend of `the shaft, thereby preventing the usual 'disagreeable rattling, andi'or relieving the said end of thelshaft from the pressure of the rubber when the couplingfpin has to `be Withdrawn. i

My invention further consists of the combination of the said cam-lever, an elbow-plate, andthe said rubber block, the. whole being arrangedin .respect to the carscribed hercafter. p p

My invention also consists in 'combining with the Asaid cam-lerer` certain armsfor retaining the coupling pin in its place,

Iii-order to enable others skilled in the art to make .riagerclip and end o f the shaft, substantially as deand use my invention, L ,will now proceed. to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which Figure l is a perspective View `of my improved carriage-coupling;

Figures 2 and 3, .longitudinal sections rof the same; and

v Figure 4, a transverse section on the line 1-2, iig. 3.

Similar letters refer to similar parts throughout the several views.

A represents part of a carriage-axle, to which is adapted the clip B, and toi-the latter is secured an eX- tension-plata'l, to the outer end of whicha camlerer, "F, is hung, by alpin, c, and `from the opposite sides of this lever project arms j', in the end of each of which is a recess, j, for a purpose explained here after. A

From the clip B project the two arms a a, between which tits the inetal end N of the shaft, the latter beingljoin'ted to the. arms by a pin, C. I

. I i's an elbow-plate, the vertical portion of which iits freelyibetwecn the arins a a, and bears against the clip and extension-plate E, the horizontal portion of the elbow-plate resting on the caml'ever F, which has a recess for receiving a projection or rib `on the under H is a'block of. India rubber, which, when the end of the shaft s'in its pla`ceandfthe cam-leveris elerated, is tightly confined between the elbow-plate and 1 In conuectingthe shaftto the abovevdescribed coup- Mling, the cani-lever is at rstdepressed to the position ,shown in gs. Vl and 2. -The end of the fshaft is then.

lintroduced between the 'arms ao of the coupling, and

lthe lpin C is inserted into its place, .after which the cam-lever F is elevatedfroin the position shown in figs. 1- and 2 to that seenin iig. 3. i In doing this, the

face (l of the cam which-is furthest from thefulcrumpin is brought to bear against the elbow-plate I, to

elevate the same, and consequently Lto compress the rubber block H against the end N ofthe shaft, thereby causing the same to bear tightly vagainst lthe pim-and thus preventing all disagreeable rattling.

Uien the cam-lever has been thus elevated, the rubber and elbow-plate aresecure'ly retained, laterally by the arms ff, and longitudinally between. the clip and portion- Il of the 1ever,`at the same time the recessed ends of the arms f f coverV the opposite ends of p the pin G, which is thusheld in its proper position.

A strap, passed through an eye at the outer end of the cam-lever, and through a similar eye, T, on the shaft,

and buckled or otherwise connected together at its opposite ends, will prevent the shafts from becoming disengaged from the carriage if the coupling-pin should accidentally break.

Vhile my improved 'coupling-bolt eiectually pre-1 vents all rattling of theshatts on the pin, the latter can be readily withdrawn, and the shafts uncoupled,

`after simply depressing the cam-lever, for by doing this therubber block is brought to such a position that its pressure against the end ot the shaft ceases, while at-the same time the pin' is uncovered, thereby permitting its ready withdrawal. y l

It will be understood that my invention can be used to advantage in coupling the' pole of a-carriage to the axle. v

l claim as my invention, and desire to secure by Letters Patentp j l. rlhe shaft, hung at its end N to a stationary pin, C; the block of rubber H, adapted tothe rounded end vof the shaft, and adjustable to and from the same;

and the cam-lever F, bearing with its inner end against a plate, I, beneath the block H, thewholebeing arranged substantially as described. u 2. The arrangement, ou the cam-lever F, of the arms f f, all4 substantially as and for the purpose set forth. l

In testimony whereof, I have signed my name to this specification, in the presence oftwo subscribing witnesses. l
